MACHINE FOR PRODUCING APE-RTURED DISKS.

SPECIFICATION forming part of Letters Patent No. 727,320, dated May 5, 1903.-

Application filed October 29,1902. Serial No. 129,256. (No model.)

provements in Machines for Producing Ap-- ertured Disks, of which the following is a full, clear, and exact description.

tured disks in a very simple and quick manner, the disks produced being accurate in shape and the machine readily operated with-' out the employment of skilled labor.

The invention consists of novel features and parts and combinations of the same, as will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a perspective view of the improvement. Fig. 2 is a frontelevation of the same. Fig. 3 is an enlarged sectional front elevation of the same on the line 3 3 of Fig. 1. Fig. 4 is asimilar view of the same, showing the working parts in adifferent position. Fig. 5 is an enlarged sectional plan view of the improvement on the line 5 5 of Fig. 1. Fig. (5 is a face view of one of the cutter-head blades. Fig. 7 is a like view of one of the spacers for the cutter-head blades, and Fig. 8 is a perspective view of a pile of apertured disks produced by the machine.

In the machine presently to be described in detail use is made of a disk-cutting device, such as a revoluble cutter-head A, for cutting the disk from a piece of wood 13, and ot'a boring device, such as a revoluble auger C, for boring a central aperture in the disk cut by the said disk-cutting device. It is understood that in referring to the piece of wood B in this specification it may bea single piece k of wood or a plurality of superposed boards or layers of wood, as indicated in Figs. 3 and 4. In the former case a single apertured disk is cut at each operation, and in the latter case a plurality of superimposed apertured disks B are produced at each operation, as is hereinafter more fully described.

As shown in the drawings, the cutter-head A operates from the top of the piece of wood B in a downward direction, while the auger O bores upward from underneath, and the g cutter-head A and the auger O rotatein op- The invention relates to woodworking ma-' chinery; and its object is to provide a new and improved machine for producing aper-- posite directions to equalize as much as possible the lateral strain incident to the cutting and boring operation.

In the operation of the machine the work or piece of wood B is placed on a feed-table D, which is fed upward by the operator pressing a treadle E to feed the piece of wood to .the cutter-head A, and at the same time the auger C is fed upward at a higher rate of speed, the feed mechanism for the auger being automatically controlled from the said feed-table D.

In detail the construction is as follows:

The cutter-head A consists of a plurality of spaced cutting-blades A of segmental shape and each formed at its lower front corner with a forwardly and downwardly extending chisel A for cutting the wood, and the front edge above the said chisel is provided with a cut-out portion A to allow the chips to readily pass upward'and out of the circular groove cut by the chisel into the piece of wood. The segmental cutting-blades A alternate with segmental spacers A, traveling in the circular groove and out by the chisels A to steady the cutter-head and to prevent wabbling of the same while cutting the disk, it being understood that the blades A and spacers A are arranged in a circle to insure the production of a perfect circular disk. The blades A and spacers A are bolted or otherwise secured to a hollow cutter-head body A screwed on the lower end of the hollow cutter-head spindle A jou rnaled in suitable bearings F F located one above the other and held on the main frame F of the machine. On the cutter-head spindle A between the bearings F F is secured a pulley G, around which passes a belt G, also passing over guide-pulleys G to a pulley on a counter-shaft to rotate the spindle A, and consequently the cutter-head A. The hub of mo the top of the bearing F is engaged by a col-- lar F, secured to the upper end of the cutter-head spindle A, so as to hold the latter against outward movement in its bearings F F (See Fig.

' The feed-table D is preferably in the shape of a block of wood set in the table-frame D, mounted to slide verticallyin suitable guideways F formed on the front of the frame F. Counterbalance-springs D are held on the frame F and connected with the table-frame D to counterbalance the latter and the table D to permit an easy upward'sliding movement of the table and the work or the piece of wood B on the operator pressing the treadle E. The latter is fulcrumed at E on the main frame F, and its inner end carries a friction-roller E engaging the under side of a foot-piece D secured or formed on the lower end of the table-frame D, so that when the operator presses the t-readle E an upward sliding movement is given to the frame D and its table D. When the operator releases the presser on the treadle E, the table and its supporting-frame slides back to its lowermost normal position by its own weight. In order to hold the piece of wood firmly down on the table D, a presser device is provided, and this device consists, essentially, of a presser-bar H, mounted to slide loosely in the cutter-head body A and the spindle A and the lower end of the said presser-bar H is formed with a central recess H for the entrance of the upper end of the auger O at the time the latter breaks through the wood at the top thereof. Chips carried upward into the recess H by the auger C readily pass out of the same through openings H arranged in the sides of the bar H. On the upper end of the presser-bar II is secured a weight H to cause the lower end of the presser-bar to press with the desired force onto the top of the piece of wood. If a single disk is cut from a piece of wood, then the cutter-head and the auger are not liable to break or chip the wood at the time they cut through the wood at the bottom and top thereof, owing to the pressure of the said pressing device, and at the same time the presser device holds the formed disk against reversion, and consequently prevents the disk from binding on the cutter-head or anger. The top of the table D is formed with a circular groove D for the entrance of the lower end of the cutterhead A, as indicated in Fig. 4. It is understood that during the upward fecdof the table D and the piece of wood held thereon the presser-bar H'on account of resting ,on the said piece of wood moves up with the latter and slides freely in the cutter-headbody A and the spindle'A.

The auger C is removably held in the up: per end of a spindle O, journaled in the bearings I 1 arranged on a slide I, mounted to move vertically in suitable guideways D arranged on the table-frame D, and the said slide I is hung on a spring I attached to the table-frame D. On the spindle 0, between the bearings I I is fastened a pulley J, around which passes a belt J, also passing over guide-pulleys J ,to then pass in a crossed position to a pulley on a counter-shaft, so that a rotary motion is given to the spindle O and the auger C, but in a reverse direction to that given to the cutter-head A. In order to feed the slide I upward at the time the table is fed upward by the operator pressing the treadle E, the following device is provided: On the slide Iis secured a rack K, in mesh with a segmental gear-wheel K, having its shaft K journaled in asuitable bearin-g D secured or formed on the frame D for the table D. A segmental gear-wheel K eX- tends from the shaft K in a diametrical direction to the segmental gear-wheel K, and the gear-wheel K is in mesh with a rack K, held vertically adjustable bysuitable means in a bracket K attached to the base of the main frame F. Now it is evident that when the table and frame D is moved upward the shaft K and its two gear-wheels K and K move bodily with the said table-frame, and

as the gear-wheel K is in mesh with the fixed.

rack K it is evident thata turning motion is given to the gear-wheels K K, so that the gear-wheel K acts on the rack K, and thus moves the latter upward,and with it the slide I, on which the said rack K is fastened. Now the slide I moves bodily with the table-frame. as the slide is hung on the spring 1 attached to the table-frame, and at the same time the slide is caused to move in the guideways D by the action of the gear described, so that the auger is fed upward faster than the table, and consequently the auger O bores the hole into the wood from underneath at the same time that the cutter-head Acuts into the wood from the top to form the disk.

The operation is as follows: When the table D is in its lowermost position, then the upper end of the auger C is below the top of the table D and within an opening therein, and the cutter-head A is a distance above the table-top to permit the operator to place the piece of wood B into the desired position on the table D, as shown in Fig. 3, and then the operator presses the treadle E to cause an upward sliding of the table D and the augercarr-ying slide I, as above explained, to cause the revolving auger to bore the piece of wood from beneath andto bring the piece of wood to the cutter-head A for the latter to cut a circular disk out of the piece of wood. As the cutter-head A and the auger O are in axial alinement, it is evident that the disk formed by the cutter-head is provided with a central aperture bored by the auger.

ter-head has cut through the piece of wood at the bottom thereof, the auger has cut through the top of the piece of wood, and then When the cutthe operator releases the pressure on the treadle E, so that the table D and the augercarrying slide I move downward by their own weight and the piece of wood moves with the table D, as well as the disk, as the latter is firmly pressed down onto the table by the presser-bar H until shortly after the cutterhead passes out of the cut, it being understood that for the purpose mentioned the lower end of the presser-bar extends normally a short distance down beyond the lower end of the cutter-head, as plainly indicated in Fig. 3. The downward sliding motion of the table- D is limited by a cushion-block L, of rubber or like material, held on the main frame F.

For producing apertured disks of larger or smaller sizes correspondingly-sized cutterheads and angers are employed.

From the foregoing it will be seen that a large number of apertured disks can be produced in a comparatively short time and without the employment of skilled labor.
